Psychiatric diagnostic frameworks serve multiple purposes. Classification of mental disorders enables clinicians and researchers to speak a common language when describing patterns of experience and behavior, guide appropriate treatment interventions, and act as a coding system for insurance purposes. The success of these classification frameworks has varied across diagnoses but in the best cases has led to improved understanding and treatment of conditions, and has helped many service users who find such classification helpful (Perkins et al, 2018).
Diagnostic frameworks are not without controversy. They have been criticized on grounds of reliability, validity, and distortions due to commercial interests (Zigler & Phillips, 1961; Frances & Widiger,2012; Bell, 2017). Perhaps most importantly there are instances where they have had, and continue to have, extremely negative effects upon service users (Perkins et al, 2018). Diagnosis is not the only way of understanding people and their experiences. Many clinicians and their clients find that attending to our personal stories and narratives is a helpful approach, and psychological formulation is one technique for bringing together information about what has happened to an individual and the sense that they have made of it (British Psychological Society, 2018).
Notwithstanding the above caveats, the ‘Recognizing…’ series from Psychology Tools is designed to aid clinicians understanding of the similarities and differences in the way that the two primary psychiatric diagnostic systems classify mental health problems. Their formatting for aid of comparison means that some detail has been purposefully excluded, and clinicians are encouraged to refer to the original source material for formal diagnostic purposes.
Insomnia is characterized by difficulty with sleep quality or quantity. Recognizing Insomnia compares the DSM-5 and ICD- 10 criteria for insomnia and the Insomnia Checklist is an assessment tool for clinicians.
The ‘Recognizing…’ series from Psychology Tools is designed to aid clinicians understanding of the similarities and differences in the way that the two primary psychiatric diagnostic systems classify mental health problems. Their formatting for aid of comparison means that some detail has been purposefully excluded, and clinicians are encouraged to refer to the original source material for formal diagnostic purposes. In particular it has been assumed that symptoms cause clinically significant distress or impairment unless otherwise stated. Information for the ‘Recognizing…’ series was drawn from:
- The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5).
- The International Statistical Classification of Diseases and Related Health Problems, Tenth Revision (ICD-10). The ICD-10 is available in two versions: (1) The Clinical Descriptions and Diagnostic Guidelines (CDDG) or ‘blue book’ is intended for general clinical, educational and service use; (2) The Diagnostic Criteria for Research (DCR) or ‘green book’ was designed to facilitate research.
